A study on one-way communication using PF_RING ZC

Commercial Off The Shelf(COTS) based one-way communication is advantageous in that support a low cost communication and high speed one-way communication. This paper provides a implementation method of one-way communication through modified device driver for COTS NIC. Then, to verify the advantage of the COTS based one-way communication method, We present a sample implementation using Intel 82580 NIC and PF_RING ZC(Zero Copy). Then, we present a possibility that can contribute to the realization of oneway communication through experiments on performance and reliability.
